SLIDING AND SWING-ING- SASH.

Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed May 4, 1908. Serial No. 430,806.

To all whom it may concern:

Be it known that I, NILs P. SJOBRING, a citizen of the United States, residing at J amestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Sliding and Swinging Sashes, of which the following is a specification.

My invention relates to certain new and useful improvements in windows and particularly in that type of Windows employing sliding and pivoted sash, or sash which may slide up and down in channels formed in the window-frame or casing, and which sash may be turned about a pivotal axis to enable the sash to swing in a horizontal plane, to facilitate the cleaning of the outside of the sash, etc.

The primary object of the present inven tion is to provide an improved mechanism for securing or mounting the sash, upper or lower, or both, so that when the mechanism is operated in one direction, the sash may freely slide up and down in its customary guides, and when the mechanism is operated in another direction, the sides of the sash are substantially removed from the aforesaid guides or channels and the sash is free to be turned about horizontally arranged pivots, in a manner well known in the art.

With the foregoing and other objects in view, my invention consists of the parts and the constructions, arrangements and combinations of parts which I will hereinafter describe and claim.

In the accompanying drawings, forming part of this specification and in which similar reference characters indicate like parts in the several views :Figure 1, is a vertical longitudinal sectional view of a window with upper and lower sashes constructed accord ing to my invention. Fig. 2, is a vertical sectional view showing one side of a sash and parts of the upper and lower rails. Figs. 3 and 4 are cross sectional views of one side of two sashes and one side of the window frame. Figs. 5, 6, 7 and 8 are details of construction.

While the present improvements may be combined with any suitable design and construction of window sash and'frame, provided the sash has an internal chamber or shown said improvements as associated with a fire-proof window wherein the sashes and the casing therefor are made hollow and composed of sheet-metal plates rolled, drawn or otherwise shaped to form the component parts of the complete structure, and fitted together in some appropriate and substantial manner. I

The window frame or casing A is formed of metal plates suitably bent and secured to form the hollow stiles a and hollow top rail 6, said frame having, also, a suitable hollow sill 0 also formed of sheet-metal. As the cross-sectional shape of the sides or stiles of this frame or casing is alike at both sides of the window and as a description of one side will answer for both, I will now refer to Fig. 3 for a more detailed explanation of said frame, but at the same time I desire to state that I do not claim the specific frame shown as an essential part of the present invention. As shown in said Fig. 3, each side or stile of the frame or casing comprises two sheet-metal plates, 0? d bent into proper form and having outstanding flanges d d bolted together and adapted to extend into the wall or structure bounding the opening in which the frame is mounted.

One of the plates d is bent to form the inner side of the stile and this plate is itself bent to form the vertical channels or guides e, e, in which the upper and lower sashes slide; the other plate 03 is suitably bent and has its outer edge flanged and riveted or otherwise secured to the first-named plate. The two plates inclose a hollow chamber in which the usual sash-weights operate, this chamber being divided vertically if desired by means of a plate f. The frame or casing may also be provided with any suitable sheet-metal or other molding, g, as shown in Figs. 3 and 4.

The sashes, S S may be of any suitable construction, but they are herein shown as being hollow and composed of sheet-metal plates suitably fashioned and fitted together to form rigid structures. Each sash has hollow sides or stiles hand hollow top and botltom'cross rails z'and a hollow meeting rm 1.

Each of the stiles, h is shown as being formed of a single strip of metal of appropriate shape in cross-section,'said stiles comprising a bent plate or strip ls whose sides are parallel and are spaced apart a distance equal to the desired thickness of the sash from front to rear, the outer edges of this plate being bent towards each other and spaced apart to form, with a channel-piece Z, a channel or opening which is coincident with the corresponding channel 6 formed in the inner sides of the window frame or casing.

The middle portion of the plate or that portion which is adjacent to the glass pane, m, is bent at opposite sides to form shoulders 'n for the abutting ends of the transverse plates 0 of the cross-rail. From this point the plate is is bent to form a fixed molding section 19, said plate being again bent outwardly to form a wall 1' for the glass pane, or panel, and thence being bent at rightangles or crosswise of the stile and finally bent to form an inclined portion 8, on the opposite side of the glass. This inclined portion has tongues t rigid with it and standing at an incline, and the wall portion 1- also has tongues 6', these tongues, 25, t, coacting with the opposite edges of the bent strip which forms the loose molding piece or section 79, said piece being fashioned with a wall, 7* which is parallel with and spaced from the wall, 1, of the fixed molding piece to form the channel for the outer edge of the glass pane, as shown in Figs. 3 and 4.

The top and bottom rails z, z" of the sashes are substantially alike being each formed of a plate bent to form parallel sides spaced apart a distance about equal to the thickness of the sash from front to rear, but having their inner edges formed with locking flanges u, adapted to interlock with similar flanges on the opposite edges of the fixed molding piece w. This piece is substantially like the molding piece 19 before described, and it coacts with the loose molding piece in to form a channel for the adjacent edges of the glass pane. These parts are substantially like the construction shown in my former patents No. 847,443, Mar. 19, 1907 and 809,145, Jan. 2, 1906 and my former application Serial No. 413,796, filed Feb. 1, 1908, and are not considered as essential parts of the present improvement. The meeting rails, 7', are also formed of sheet-metal plates, y, having the general characteristics of the corresponding plates, and molding sections of the stiles and rails before described, except that each meeting rail is bent to form a locking shoulder, .2 which interengage when the sashes are closed, as in Fig. 1.

The frame or casing will be provided with a top molding section 9' and will contain hangers h for the pulleys P over which the weight cords TV are designed to run.

Having thus described in more or less general terms the construction of window frame and sashes shown, I will now more particularly describe the features which form the essential parts of the present im provement.

In the vertical channel in the side edge of the sash is located a bent plate which forms the channel-strip 10 between the parallel sides of which are mounted the rollers .11 which are adapted to travel in contact with the grooves or channels, a formed in the inner vertical sides of the window frame or casing, said channel-strip, 10, adapted to be moved horizontally in and out of the said groove or channel by means which i will presently describe.

Back of the channel strip 10 and fixedly secured to the sash is a vertical strip or plate 1 which is bent to form the walls of the vertical groove or channel in the side edge of the sash and in and out of which channel the channel-strip 10 is movable, it being moved outwardly to carry the rollers. 11, into the guide grooves or channels of the frame or casing, as in Fig. 4 when the sashes are to be lowered and raised, and said channel strip, 10, being retracted out of the channel or groove in the frame or casing and into the groove or channel of the sash, as in Figs. 2 and 3 when the sash is to swing about its horizontal pivots, as I will presently describe.

That the foregoing operation may be effected, I attach to the back of the fixed plate 1 a socket piece 12 which projects through an opening in said plate and through a like opening in the back of the channel strip, said socket having titted to it the pivot pin 13 which forms the axis about which the sash swings in a horizontal direction, said pin having secured to its outer end a split clamp, let, which forms an ttaehment for one end of the weight cord In order that the clamp may be tightened upon the pin, when desired I employ the screw, 15, which passes through the split members of the clamp, as shown in Fig. .7. A screw 16 also passes transversely through one side of the socket piece 12, and engages the pivot pin to hold the same to the socket. In addition to the foregoing, a pin, 17, is driven into matching grooves in the adjoiuing faces of the pivot and socket and is designed for the purpose of forcing the outer end of the pivot pin into contact with the bottom of the vertical groove or channel in the window frame or casing.

Fixedly secured to the aforesaid stationary plate or strip 1 is a bar or bracket [8 the lower portion of which is recessed or forked and mounted between said forks is a bell-crank lever 19, whose angle is pivotally hung upon a transverse pin, 20.

The short arm of the bell-crank lever is secured to a channel-strip, 21, which serves l l (i substantially as a parallel-bar, it being understood that both the upper and lower ends of each side of the sash will be provided with corresponding bell-crank levers and accessories as before described, the said channel-strip, 21, affording means for operating the devices at both ends of the sash in unison. An angle-bar, 22 is secured on the outside of the movable channel strip, 10, and its horizontal member extends through openings in this strip and also in the fixed strip 1 and has its inner end provided with a T-sha ed head forming the recesses 23. The bel -crank levers, 19, have their lower ends or long arms forked and these forks are designed to straddle the T- shaped head of the angle bar 22 so that one fork loosely operates in each of the notches therein.

A bar, 24., has one end connected to the forks of the bell-crank lever 19 at the lower end of the sash and thence extends horizontally across the lower rail of the sash to say the center of the sash, and has its opposite end connected to one end of a centrally pivoted lever 25, the opposite end of this lever being designed for connection with similar connections at the other side of the sash, it being understood that each side of the sash and the frame or casing will be supported with the channel-strip and actuating parts before mentioned, and that the mechanisms at both sides of the sash will be operated from the central lever 25 whose pivot is a shaft extending transversely of the sash and has an operating finger piece 26 on its outer end.

The operation of the foregoing mechanism is substantially as follows: When the finger piece, 26, is turned, it rocks the centrally pivoted lever, 25, and causes its ends to move in opposite directions thereby moving the connecting bars 24: outwardly, as shown in dotted lines in Fig. 1. This movement causes the lower ends of the lower bellcrank levers 19 to be moved from the full line position in Fig. 1 to the dotted position, these levers turning upon their pivots, 20 and the short-arms of the levers being moved to the dotted position thereby causing the channel strips or parallel bars 21, to move downwardly and to transmit motion to the bell-cranks at the upper end of the sash. As the lower bell-cranks are forced outwardly these lower ends contact with the walls of the notches 23 formed in the T- shaped heads of the angle-bars, 22, and as these bars are connected with the movable channel strips, 10, it is evident that the pressure upon the angle-bars causes the channelstrips to be moved outwardly substantially from the channels formed in the sides of the sash and into the channels e, formed in the frame or casing, the rollers, 11, carried by said movable channelstrip being thus carried into contact with the bottom of the channels 6, in the frame or casing and serving as guides for the vertical movements of the sash. When the parts are in this position the sashes may be raised and lowered at pleasure and they will operate the same as any sliding sash.

If it is desired to clean the outside of the window or to turn the sash about its horizontal center, the finger-piece, 26, is operated to move the mechanism from the dotted position in Fig. 1 to the full-line position when the lower bell cranks, by engaging the other walls of the recesses in the T-shaped heads of the angle-bars, 22, will pull the movable channel strips, 10, with their rollers out of the grooves or channels in the frame or casing and into the channels in the side edges of the sash. When the parts are in this position, the sash is free to swing upon its horizontal pivot pins 13, while suspended from the usual weight-cord or chains. It will be understood that both the upper and lower sashes may be pivoted with the mechanisms before described, although I have shown but one sash having said mech anism.
